拦截GWT RequestFactory请求 [英] Intercepting GWT RequestFactory requests

问题描述

我想拦截这样的调用：

有没有办法在客户端拦截RequestFactory请求？

  dummyRequest.dummyOperation（）。fire（new Receiver< String>（）{
 @Override 
 public void onSuccess（String response）{
 } 
}）; 
  

这个想法是在与服务器通信时显示一些加载指示。

您可以覆盖默认的传输实现并在RF初始化期间传递它：

 
 
 code> SampleRequestFactory factory = GWT.create（SampleRequestFactory.class）; 
 factory.initialize（new SimpleEventBus（），new DefaultRequestTransport（））; 
  

您可以继承DefaultRequestTransport并覆盖方法

  send（String payload，TransportReceiver receiver）
  

在调用超级实现之前进行一些处理，并使用委托包装TransportReceiver来处理结果。

Is there a way to intercept RequestFactory requests on client side?

I want to intercept calls like this:

dummyRequest.dummyOperation().fire( new Receiver<String>() {
  @Override
  public void onSuccess(String response) {        
  }
});

The idea is to show some loading indication when communicating with server.

解决方案

You can override the default transport implementation and pass it during RF initialization:

SampleRequestFactory factory = GWT.create( SampleRequestFactory.class );
factory.initialize( new SimpleEventBus(), new DefaultRequestTransport() );

You can inherit from DefaultRequestTransport and override the method

send(String payload, TransportReceiver receiver)

Do some processing before calling the super-implementation and wrap the TransportReceiver with a delegate to handle the result.
